Main Stuff

There are two ways you can talk to the KUBE API.

Kube-proxy

Start a kube proxy server which will act as a reverse proxy for the client.

NOTE: Specific examples given for options, flags, commands variations, etc., are not comprehensive.

NORMAL MODE

Vim has 2 main "modes", that chance the behavior of all your keys. The default mode of Vim is Normal Mode and is mostly used for moving the cursor and navigating the current file.

Some important (or longer) commands begin with ":" and you will see the text you enter next at the bottom left of the screen.

:q[uit] - quit (the current window of) Vim. ("Window" here is internal to Vim, not if you have multiple OS-level windows of Vim open at once.)
:q! - force quit (if the current buffer has been changed since the last save)
:e[dit] {filename} - read file {filename} into a new buffer.

Creating the patch

git format-patch -1 <sha>
OR
git format-patch -1 HEAD

	Demo of how to access the protected branches API, currently in preview.
	See https://developer.github.com/changes/2016-06-27-protected-branches-api-update/
	Note that you get a 404 if you attempt to get the protection of a branch on a
	repo that your token actually works for (it's not well-defined behavior, but
	it's what happens).
	Note that for this to work on non-unix systems, AUTH_TOKEN must be set.
